EU-LFS 2016 contains the Ad hoc module on young people on the labour market.
Geographical Coverage
The EU-LFS 2016 covers all 28 EU Member States as well as Iceland, Norway and Switzerland.
Time Period Covered
The EU-LFS 2016 "is designed as a continuous quarterly survey with interviews spread uniformly over all weeks of a quarter. Each reference week starts on Monday and ends on Sunday. The first week of a year or quarter is defined as the week that includes the first Thursday of the year or the quarter. All countries conduct the LFS as a continuous survey."

Weighting: Method
"The initial weights are calculated according to the sample design, with all persons within the same PSU having equal design weights. The design weights are adjusted using the data of response level in each stratum for each wave and each survey technique (CAPI/CATI). These quarterly weights are then adjusted on the basis of demographic data and data of the State employment agency and of the State Revenue Service. Yearly weights are calculated as quarterly weights divided by four.
For adjustment of the quarterly weights demographic data are broken down by the type of municipality (Riga, cities, towns, rural areas), as in stratification, 14 age groups and sex as well as in NUTS3 (6 regions), 3 age groups, eight cities of Republic, the information from the State employment agency by sex and 5 age groups and the information from the State Revenue Service by sex and 7 age groups.
All persons within the same household have equal initial and final weights." (Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries. Main characteristics of national surveys, 2016, p. 33)

"There are defined weighting groups regarding non-response, and response rates are calculated for each of these groups. The urban part of each 21 county form one group while the rural parts in each county form the second group. As there are 21 counties, multiplying 2 groups (urban and rural) gives 42 groups within counties for defining non-response rates (and calculating response rates in each one). Non-response weights are inverse value of these response rates. They are also equal for each segment." (Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries.

Coverage Adjustment Weight: Method
"Distributions of the 5-year age groups, gender, NUTS2 regions and household size) for the subsample of respondents were calibrated to known auxiliary information from Census 2011. It reduced sampling error, effecting the ‘old’ weights, but in limits of previously defined constraints in CALMAR software. Bounded linear method was used for calibration, and lower limit was set on 0.5, and upper on 3." (Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries.

"Variables used for correction for non-response are derived from the sample base: size of urban unit, number of rooms in the housing, type of housing (individual house, building, …), number of new dwellings and region, income of the households (deciles), age of the inhabitants, social housing or not, rented accommodation or property for Metropolitan France; type of housing, micro-region (infra-NUTS3), being respondent or not during the previous quarter for overseas departments." (Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries. Main characteristics of national surveys, 2016, p. 25)
Coverage Adjustment Weight: Method
"Weighting procedures are different for Metropolitan France and overseas departments. For Metropolitan France, a unique calibration is performed on each wave both to correct biases induced by non-response and to get consistency with external margins. Another correction for non-response is made using the answers to the “non-response survey” (NRS): the employment and unemployment ratios are adjusted to the ones obtained when including the respondents to the NRS survey within the LFS. For overseas departments, weights are first adjusted to correct for non-response by using an estimation of response probabilities, and are calibrated in a second step in each department on external margins."

The registers which are used to obtain the auxiliary variables are the Register of Total Population (RTB), the Employment Register (RAMS) and the Swedish Public Employment Service´s register of job-seekers (SOK).
Each month the last wave of the individual LFS-sample is used as the starting point for identifying sampled households, i.e. the household sample is a network sample. The weights are based on the calibration approach for two-phase sampling in Estevao and Särndal (2002). Design weights according to the network sampling design, adjusted for nonresponse at the household level, are used as starting weights in the calibration. Only information at the individual level is used in the calibration." (Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries.

"The adjustment procedure is based on a three-stage a posteriori stratification. In each case, figures are based on independent demographic estimates.
The stratification variable for the first stage is the Local Authority District or Unitary Authority. This stage makes it possible to make adjustments for different rates of non-response in the various local authority areas and ensures that the results are geographically representative.
The second-stage variables are sex and age group (0-15, each year of age in the 16-24 group and 25 +). This stratification is intended to ensure that the age profile of the 16-24 year olds is correct at national level.
The variables in the third stage are region, sex and five-year age group.
The three stages are applied by means of an iterative procedure designed to ensure that the estimates are consistent with the stratification variable sets." (Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries. Main characteristics of national surveys, 2016, p. 61)

(Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries. Main characteristics of national surveys, 2016, p. 29)
Coverage Adjustment Weight: Method
"Starting from intermediate weights, final grossing weights are obtained solving a minimisation problem under constraints. The function to be minimised is the distance between final and intermediate weights; the constraints regard the estimates of some auxiliary variables that have to be equal to the totals in the reference population derived from external sources. Main constraints are population by gender and age groups at NUTS 2 level and population by gender and age groups of different width at NUTS 3 level. Final weights ensure that all members of a given household have the same weight." (Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries.

"The weights are computed using a four-step procedure. First the initial design weights are calculated for dwelling units, i.e., the reciprocals of the selection probabilities for the final sampling units in each stratum. Secondly, the weighted response rates are calculated for sampling units stratified a posteriori by six place-of-residence categories. Thirdly, the initial weights are adjusted by the response rates.
The final step consists in modifying the adjusted weights using the population estimates stratified a posteriori by the urban-rural division, sex and 12 age groups plus three age groups for children living in the surveyed households separately in each voivodship."

Projections by age and region are distributed by stratum in proportion to the population of each stratum.

In this stage biases because of non-response are reduced. For this, information on gender, age, ethnic background, place of residence and some other regional classifications are used. In addition, administrative sources on the income and registration at unemployment office are used. Also information on the correlation in the panel-overlap between subsequent quarters is used and all waves together are weighted in one step."

For working-age persons the subgroups by sex, age (five-year age groups), place of residence (urban/rural area, 15 counties (NUTS 4 level) and the capital city) and Estonians/non-Estonians are considered. For this purpose the linear consistent weighting method is applied.
For non-working-age persons the non-response adjusted household's weights are calibrated by sex and five-year age groups." (Eurostat (2018): Labour force survey in the EU, candidate and EFTA countries. Main characteristics of national surveys, 2016, p. 17)
